A furore developed following the publication of the article last Sunday, which also said Arabs "murdered more than 3,000 civilians on 11 September" and then "danced in the streets" to celebrate.

Mr Kilroy-Silk also claimed his secretary mistakenly sent the column to the Sunday Express instead of one on foreigners using the NHS, as he had planned.

He said the article, which was originally published during the Iraq War in April of last year, had not caused offence at the time and was intended as a criticism of certain Arab regimes, and not Arab people.

Mr Kilroy-Silk said: "I clearly do not believe that
all Arabs are suicide bombers etc. That would be stupid.

It says he believes the BBC should have stood by him, while distancing itself from the Sunday Express piece, which bore the headline "We owe Arabs nothing".

The presenter told this week's Sunday Express: "I'm disappointed that the BBC didn't feel able to support me.

"I said to it that I understand its need to say that the column is nothing to do with it and the views are nothing to do with it, but my impartiality on the programme has never been a problem."

'Racist nature'

On Saturday campaigners rejected a statement in which the presenter said he "regretted" the article.

Iqbal Sacranie, of the Muslim Council of Britain, said: "The article itself I think is of racist nature and it is only appropriate that there should be a full apology so the matter can then rest and hopefully
not be repeated again."

But Judith Vidal Hall, the editor of Index on Censorship magazine, said taking people off air was not the way to tackle racism.

She told BBC Radio 4's Today: "I don't think in a country with a free media and a plural society and a commitment to a right of reply, you ever solve anything by banning, removing, censoring."

Police are investigating Mr Kilroy-Silk's comments after a complaint by the Commission for Racial Equality.

BBC Breakfast will continue for an extra half hour on BBC One, to 0930 GMT, while Kilroy is off air.
